Hi, all. This is probably a simple matter, but I thought it worth asking, anyway. I've written a short story, which I intend to direct, shoot, and edit. Before I wrote it, I put an ad out for someone to co-write, because my stories have a habit of being crap. The script I have needs adjustments, but is mostly written, and I don't want to hand a copy over to the guy who answered my ad, until I have his signature on some kind of contract, so he doesn't claim to have written it, when he's only made a few tweaks. Is there some standard contract I can use, include by reference, or otherwise build on, that will ensure he has the right to work on it, be credited for his input, etc., but not take off with it and make derivative works, or otherwise plagiarize it? I live in the UK, which is where all work for the entire project will take place. At the moment, I have no plans to release the film. It's just to get me into university. But I think the university puts student films on the net, so I need to take that into consideration in my contracts. I hope this makes sense, and would very much appreciate any help I can get on this matter. Thanks in advance! TT
